As part of a recent exhibition at Chris Beetles fine art gallery, they printed up a small 210mm x 210mm book of Kenna's work. The book comes with a price list for his prints and also, what I liked the most, was that each image had the title written in Kenna's own hand. Which is rather unusual. It's also pretty cheap at £10 a copy.
It by no means as beautifully printed as the Nazraeli titles are, but it's an unusual offering, and one for those who would like to have something by Kenna in print, or maybe for those fans like myself, who just have to own anything he does :-)
If you'd like one, then best get it at http://www.chrisbeetlesfinephotographs.com/publications/michael-kenna.html.
